1. Dan runs 10 miles in 80 minutes. How many minutes does he take per mile?
2. Yoko bought 14 pounds of rice for $8. How many dollars did she pay per pound of rice?

Answer 1

Explanation:

10 miles in 80 minutes = 1 mile in x minutes

10/80 = 1/x

10x = 80

x = 80/10

x= 8 miles per minute <===

======================

14 lbs rice for $ 8 = 1 lb rice for x $

14/8 = 1/x

14x = 8

x = 8/14

x = 0.57 per lb <=== thats 57 cents per lb
